Quick question...
Where can cellular modem options for Neo900 be discussed? A comparison of them made? It may be an obvious reason which I do not notice, but why all the modems listed are gemalto's?

For example:

PHS8 and PXS8 have only GPS, no backup. PLS8 has GPS/AGPS/GLONASS. Qualcomm's MDM9625+ and MDM9225+ have GPS+GLONASS+Beidou.

PHS8 and PXS8 have 3G+2G+GPRS/EDGE. PLS8 has GPRS/EDGE+4G(Quad Band LTE, Tri Band UMTS/DC-HSPA+).
PXS8 has Dual-Band CDMA. PHS8 has TCP/IP.

Qualcomm's MDM9625+ and MDM9225+ have GSM/GPRS/EDGE, TD-SCDMA, LTE Adv. Cat 4, LTE FDD/TDD CAT 3, SVLTE-DB, HSPA+ Release10, EGAL.
MDM9625 is considered a bit more advanced (world mode). I am not sure if I understand correctly, but the specification sheet includes WiFi for all Qualcomm MDM chips (it's like having FM radio transceiver and Bluetooth on one chip: very confusing).

I am confused with all these bands, but 'world mode' sounds interesting. I am personally more interested in GPS+GLONASS+Beidou bit.

All of the variants (PHS8, PXS8 and PLS8) support GPS and GLONASS, both with assistance mode.

Alright. I was looking only at the first page of the pdf file; I should have scrolled down.

Interesting... Would Qualcomm's variants be pin-compatible with each other, too? Either way, it's awkward when different chipset makers have different pins, as if they just wanted to stop users from jumping between different manufacturers.
Best wishes. Thank you.

I've been trying to figure out which LTE modem I will need in Colombia but I'm quite confused by some of the information I've been reading.

There are several LTE operators here which as I understand it operate LTE on either AWS/Band 4 (1700MHz) or Band 7 (which most of the websites here report as 2500MHz but some report it as 2600MHz).

For those operators on 1700MHz, I would go for the PLS8-US modem which would be the safest option.

My confusion relates to Band 7. 2500MHz is not listed in the PLS8 data sheet however it does list Band 7 and 2600MHz for the PLS8-E modem. Would you expect the PLS8-E to work with these operators?

I would prefer to go for the PLS8-E modem (if compatible here) as it would also be the best choice for if/when I return to Europe. Band 7 is also the band offered by the operator that offers the best TV package here (for football) which would be appealing should I at some stage want to go for a quadruple play (convergence of services) solution.
